Alex Hall

Alex Hall’s research is focused on reducing uncertainties associated with global climate change and involves a global perspective on earth’s climate. The overarching goal of his global climate research is to determine what controls the climate’s sensitivity to external forcing. His work also focuses on developing regional earth system models and studying the climate from a regional perspective to lay the groundwork for an understanding of climate change at scales most relevant to people and ecosystems.

Ondine S. von Ehrenstein

I specialise in global reproductive, perinatal and child health, including birth outcomes, neurodevelopment, autism, cognition, and asthma. My work emphasizes the life-course approach, focusing on the early life period as it sets the stage for life long health. My research involves large population studies to examine linkages between prenatal and early life environmental, lifestyle and community factors, and reproductive, childhood and population health. My current research takes place internationally and in California. The overarching aim of my work is creating population based evidence that can impact policies and translate into community based prevention.
